The difference between the normal bulbs at the petstore and the ones at home depot are the pet store ones burn out faster and they have some stupid coating on them that does jack all and of course the price
ceramic bulbs are poo IMO they dont project heat for a far distance they use more power to maek teh same heat as a heat pad they Dry the air in the tank (it can be good or bad pending the animal)
Heat pads are much better then ceramics imo
